Hyundai Mobis has developed a foldable steering system technology. The system is receiving attention as a feature that is optimized for future mobility vehicles as it can allow for more space in the driver’s seat and bring about design innovation.
The Hyundai Mobis foldable steering system features a steering wheel that can move forwards and backward up to 25cm. The development of the technology approximately took two years for completion as it is a wholly new technology that has never been globally commercialized before, with the company currently filing patents globally.
To develop this system, Hyundai Mobis designed new core parts of a steering system, including a column and a reaction force control device, and applied a sliding rail mechanism, securing system durability and reliability.
The system enabled the application of assorted designs, including a storage type where the steering wheel can be retracted into the dashboard, as well as the foldable one. This means that an innovative driver’s seat, which we would only be able to see in future concept cars at a motor show, is now coming closer to being on the road.
The new foldable steering system is also compatible with the Steer by Wire (SBW) steering system the company had developed before. The SBW system controls steering with electrical signals by connecting the steering wheel with a device designed to deliver the steering force generated from the steering wheel to the wheels.
The SBW system enables the provision of optimal steering performance on the various driving conditions and minimizes the vibrations that come from a rumble strip or a speed bump to the steering wheel, allowing the driver to drive in a comfortable and stable manner.
Hyundai Mobis plans to actively respond to the self-driving car market and the future mobility market, including PBV, by further improving its competitiveness with various future technologies, such as the foldable steering system. It also plans to promote the foldable steering system as a major export item.
